PHILADELPHIA—Two Pennsylvania lawmakers plan to introduce a bill that would prohibit mental health providers in the commonwealth from trying to change the sexual orientation of gay minors.

State Reps. Brian Sims (D-Philadelphia) and Gerald Mullery (D-Luzerne Country) said in a press release their measure would prohibit mental health providers in Pennsylvania from engaging in “conversion therapy.” State Sen. Anthony Williams (D-Philadelphia) has introduced a similar bill in the state Senate.

“It’s time to protect Pennsylvania children from this quackery that can inflict years of harm for those who manage to survive it,” Sims said.
